' ANTISKID AND nun-onams.

citizen of the United States, and resident of Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Antiskids and Mud-Chains,-of which the following is a specification. g

This invention relates to an attachment for pneumatic-tired wheels which attachment is designed to function either as an anti-skid when on pavements, "or as a trac tion-maker when the vehicle is stalled in mud or sand. Briefly stated, the device consists of a pair of segmental, rigid attachment-bars, a plurality of transverse chains connecting such bars, and the fastening means hereinafter described.-

The object of the invention is to provide a device of the character named which is easily and; quickly attachable to a vehiclewheel without the use of snap-hooks or any other minute or troublesome device, and which is attachable to the upper portion of the wheel by a person standing on the running-board or step of the vehicle. A special advantage of this feature is that the device may be applied after the car has been stalled in mud or sand. Moreover, when intended for use on hard smooth wet pavement, it is obvious that my device is more easily placed and removed than are the well known annular chains sold for the purpose.

A preferred embodiment ofthe invention is shown by the accompanying drawings, in which Figure 1 is a side elevation of one unit in fastened position upon a portion of a tire and its rim; F i 2 is a transverse section on line Il-Il of Fig. 1, indicating threesuccessive preliminary positions of 'the lever-fastener in dotted lines; Fig. 3 is an inside plan view of the unit in final position; Fig. 4 is an enlarged detail view of a portion of the lever-fastener. Fig. 5 is a detail view of a modification wherein a hook may be cast upon the side-bar 1 in lieu of an eye, such hook being adapted to be closed upon a link" as indicated in dotted lines.

The inner face of each of the rigid bars 1 is fiat; the outer face of each bar is cast with a continuous stiffening rib 2. A series of spaced eyes 3 are cast on the convex edge or rib of each bar 1. Each eye 3 receives a terminal link of a chain 4, the two Specification of Letters Patent.

bars being thus connected by a series of transverse chains.

In each bar 1 is a central perforation 5 for attachment of the fastening members to be described. One fastening member consists of a'short heavy chain 6, linked in eye of. one bar- 1. To the other end of this chain s llnked an eyebolt 7' on which is a wmgnut 8. Eyebolt 7 passes loosely through a hole in one end of a rigid rimplate 910, which is provided with a pair of flanges 12, adapted to engage the sides of a felly 13 as shown. Plate 9-10 is extended longitudinally in both directions, its extens ons 10 affording larger bearingsurface upon the felly. The entire inner face of said plate and its flanges 12 is provided w th a thick leather lining 14.

The side of plate 9 opposite eyebolt 7 is formed with a lug 15in which are formed a concavlty shown on .Fig. 2 of the drawmg, a small interior catch 17, and an exterior catch 18.

Connected to the central eye 5 of one attachment-bar 1, is an eyebolt 19-20 made n two parts, the. part 20 being threaded into the part 19, whereby the length of the bolt as a whole is adjustable. part 20 is connected by a link -22 to an eye 23 on one end of a rectangular link 24:, through the outer end of which passes a fulcrum-pin 25, on which ,is rockably mounted the lever-fastener 26. By this term I mean acombined lever and fastener, and not a fastener for a lever. llhis fastener comprises a lever or handle 26, a heavy lug 27 providedwith a shoulder 28,

l and a smaller lug 29 formed with a shoulder 30.

Rim-plate 9 is formed with a raised rib 31 at each side oflever'26, to guide said lever laterally, or rather to form a more fixed seat for same when closed.

Eye 21 on crum. If the reach is too long or too short,

adjustment is easily made by turning the screw 20 (with its attached parts). Con- .tinuing the closingmotion of the lever 26, its large lug 27 enters the concave 16 in lug 15 of plate-9, its shoulder 28 engages If the parts are found not to be sufliciently tight upon the tire, the tension may be increased by adjusting the two-part eyebolt 19-20 which acts like a turnbuckle.

The end of the handle 26 in closed position is so close to the Wingnut 8 that the latter can turn backward only slightly, its

"further rotation being prevented by one of 15 its Wings impinging on the end of said handle. Thus, the loosening orloss of the vvingnut is automatically prevented.

After one unit has been mounted on a Wheel, it is obvious that the Wheel may be turned and that one or more additional ner to other segments of the Wheel.

The attachment-bars 1 may be made in various lengths Without any departure from the construction herein described, though of course the number of cross-chains in a unit may vary.

Having thus described the invention, What I claim, and desire" to secure by Letters Patent, is:

lln combination in a device of the kind described, a rim-plate, lever contacting said plate, fastening means tensioning the lever. against said plate, other fastening means comprising a bolt passing freely through a hole in the rim-plate, and a Wing-nut on said bolt at the outer face of said plate: the free end of said lever being positioned so as to provide a latch to prevent full rotation of said win -nut.
